Overview

E501II - Potassium hydrogen carbonate

Potassium hydrogen carbonate (E501ii), also known as potassium bicarbonate, is a white, odorless powder that releases carbon dioxide when it reacts with acids. In food, it mostly works as a low‑sodium leavening agent and a mild acidity regulator in baked goods and drink mixes. It is vegan and gluten‑free by nature.

E575 - Glucono-delta-lactone

Glucono-delta-lactone (E575) is a mild acid that slowly turns into gluconic acid when mixed with water. Food makers use it to control sourness, help dough rise, and set or firm foods without a sharp drop in pH. It is widely approved for use in the U.S. and the European Union.

Popular questions

Is potassium bicarbonate good for you?
In the small amounts used in foods, potassium bicarbonate (E501ii) is generally recognized as safe and can help reduce sodium compared with baking soda. Large amounts may raise blood potassium—people with kidney disease or on potassium‑sparing medications should avoid high intakes.
Is potassium bicarbonate baking soda?
No—baking soda is sodium bicarbonate (NaHCO3); potassium bicarbonate (E501ii) is a sodium‑free alternative used similarly as a leavening agent.
What are the two sizes of potassium bicarbonate portable extinguishers?
Common portable potassium bicarbonate (PKP) extinguishers are typically 18‑lb and 27‑lb units.
Is potassium bicarbonate the same as baking soda?
No—baking soda is sodium bicarbonate, while potassium bicarbonate (E501ii) is the potassium version and a sodium‑free substitute.
What is potassium bicarbonate used for?
In foods it functions as a leavening/raising agent, acidity regulator, and stabilizer, often as a sodium‑free alternative to baking soda. It’s used in baking powders, low‑sodium baked goods, and to reduce acidity in products like wine and cocoa.
